Beskrivelse
This book analyzes critical topics that include the importance of conservation and the immediate and long-term threats posed to our air, forests, oceans, and even the soil beneath our feet, which, interestingly, contains in one tablespoon more organisms than all humans on Earth. Readers also learn how people are putting grey water to use (some water that flows down our drains) and how one young man developed a system to clean up half the garbage in the oceans within five years. Also included is an insightful 'Myths and Facts' section, along with '10 Great Questions to Ask Your Science Teacher.'
